"Hard" and "soft" are definitely well-established terms for
describing bounces. I think that "transient bounce" is a weird
choice, though. It's not a bounce, and if it was, a transient bounce
would sound, to me, like a soft bounce. It's just a DSN that isn't a
bounce reporting DSN.
How about trying to define some terms?
If there is a good summary on the web, please give me a pointer.
These are my guesses about how the terms could be defined...
reply:
The email was sent in response to another message
auto-reply:
A reply generated automaticly by a program. May in some instances be
sent upon human intervention.
transient:
The email has not yet reached the recipient
bounce:
The email will never reach the recipient
hard bounce:
No recipient with the given address exist
soft bounce:
Recipient exist, but message could not be delivered
delivered:
The email has reached the recipient
vacation:
The email has reached the recipient? But will not be read until a
certain time
challenge response:
A transient status, needing an action from your part
address changed:
May or may not also be a bounce
message changed:
The message was forwarded, but with some changes, such as attachement
removal
block:
Message could have been delivered but was not accepted
message block:
The message was bounced based on the properties of the email
server block:
The message was block based on one of the sending servers
That would give the tree: (Using # * + - for indicating levels, in case
of bad email reformatting. ;-)
reply
# auto-reply
* bounce
+ hard
- address changed
+ soft
+ block
- message
- server
* transient
+ challenge response
+ message changed
* delivered
+ vacation
+ address changed
+ message changed
And some common informational bits given in relation to one or more of
the above would involve: spam, virus, message size, server errors and
mailbox full.
A lot of these are interconnected. I'm not sure how to split it up in a
good way. One module may want to check the response from another module.
But std_reason should be expanded to give room for more information.
